Einstein says that e=mc^2, and you assign a graduate student to look into this
for a few minutes, and he can't figure it out, so you tell him to look at it for
a day, and since he can't, you assume that Einstein is wrong?

This analogy stretches, I admit.

Not every problem is solvable in a short time.  If you search for 8 hours you
are only searching a few more plies than if you search for 2 minutes.  You're
just doing a little more of the same old stuff.

Maybe the pawn sacrifice doesn't work, but the argument against it is going to
be a chess argument, not a "I searched this for a year and didn't find it"
argument.
